Abstract

A system-on-chip includes a clock generation circuit configured to generate a reference clock of a first phase; a transmission circuit comprising a serializer configured to serialize data according to the reference clock of the first phase; a reception circuit comprising a clock data recovery (CDR) circuit configured to receive the serialized data and generate a first recovery clock and recovery data; and a Built In Self Test (BIST) circuit including a CDR performance monitoring circuit configured to generate a control signal provided to a delay controller configured to delay a clock signal by a preset phase difference, and the delay controller configured to delay the clock signal in response to the control signal by the preset phase difference and provide the delayed clock signal to the transmission circuit.
